so if the customer expects you to take an hour for £10 - is that how long you take?
Their is a fine balance as to what's the right speed, whether your on your own or 2 men, I've had customers that expect me to be on their house for at least an hour when paying a fiver
The more you do this job, and more importantly the more you clean a property the quicker you become that does not make you worse, or skimping just well practiced and good.
Go change a tyre on your car and time it, then do it 40 times a day for a week then retime it I wonder if it will be the same or quicker.
As ex military I'm sure you'd appreciate constant practice makes you better
